Nodule Reduced by 51.9%! Imbioray tiNK Opens a New Path for Thyroid Nodule Intervention

In recent years, thyroid nodules have become a common finding on physical examination reports, and can be called an endocrine health threat for adults. Multiple large-scale epidemiological and physical examination data show that the standardized detection rate of thyroid nodules in China has reached 48.7%, meaning nearly 1 out of every 2 adults is diagnosed with thyroid nodules. Based on the total population, the number of people affected by thyroid nodules in China has exceeded 100 million, and the detection rate is still rising year by year.

More notably, the incidence of thyroid nodules shows obvious population characteristics: the detection rate increases significantly in people over 35 years old, and is much higher in women than in men. People with long-term staying up late, excessive stress, anxiety, irregular diet and work-rest schedule are high-risk groups for thyroid nodules.

Although more than 90% of thyroid nodules are benign, with malignant nodules accounting for only 5%–15%, benign nodules are not completely harmless. Some nodules continue to grow, compressing the trachea and esophagus, causing swallowing discomfort, breathing difficulties and hoarseness. There is also a certain risk of malignant transformation, leaving countless patients in the dilemma of “being diagnosed but hard to manage”.

Traditional Treatment Dilemma:

Either Over-Treatment or Passive Waiting

Traditional clinical treatments for thyroid nodules have obvious shortcomings, putting both patients and doctors in a dilemma. The core problems focus on three aspects:

1.Surgical resection: high trauma, many sequelae, more harm than good

Surgery was the main method for treating large nodules or suspicious malignant nodules. Although it can directly remove lesions, it has prominent drawbacks: permanent scars affecting appearance; high risk of recurrent laryngeal nerve injury during surgery; complications such as hypocalcemia and hypothyroidism, severely impairing quality of life. After resection of part or all of the thyroid tissue, most patients require lifelong thyroid hormone medication, regular follow-ups and dose adjustments, restricting daily life. Surgery is clearly over-treatment for most small benign nodules.

2.Minimally invasive ablation: limited application scope, still risk of injury

Microwave and radiofrequency ablation are minimally invasive treatments with less trauma than open surgery, but they are still invasive procedures. They are only suitable for benign nodules of specific size and location, with limited effect on multiple nodules or ill-defined nodules.

Ablation may damage surrounding normal thyroid tissue, with risks of local edema, pain and residual nodule recurrence after surgery. It is not suitable for all thyroid nodule patients.

3. Regular follow-up: plagued by anxiety, risk of nodule progression

For small benign nodules without signs of malignancy, regular re-examination and conservative observation are mostly recommended clinically, which is essentially “passive waiting”.

Patients suffer long-term anxiety about nodule enlargement and malignant transformation. Nodules do not disappear spontaneously; some grow slowly or even change in nature during observation. Intervention after deterioration often misses the optimal timing.

In recent years, immune cell therapy represented by NK cell therapy has opened an innovative path for nodular diseases, showing promising application value and clinical effects in numerous studies.

Core Advantages of NK Cells

in Thyroid Nodule Intervention

· Precise targeting and immune microenvironment regulation:

NK cells can precisely identify abnormal hyperplastic cells in the thyroid, inhibit continuous nodule growth, secrete various cytokines, regulate local immune balance in the thyroid, relieve chronic inflammation, and block the formation and progression of nodules fundamentally.

· Mild nodule reduction and lower malignant risk:

Based on improved overall immunity, it gently reduces nodule tissue and lowers the risk of malignant transformation, especially suitable for long-term management of patients with benign, multiple or small nodules.

· No obvious side effects, wide applicable population:

NK cells rarely cause cytokine release syndrome or graft-versus-host disease, with no severe adverse reactions. Only a few patients experience mild fatigue or low-grade fever, which resolves spontaneously in a short time. It is suitable for all types of thyroid nodule patients.

· Non-invasive intervention, no impact on daily life: Different from invasive treatments such as surgery and ablation, NK cell intervention does not damage normal thyroid tissue, avoiding sequelae such as scars, nerve injury and lifelong medication. The process is comfortable and does not affect normal life and work.

Latest Imbioray Case:

Nodule Reduced by 51.9% After 3 tiNK Interventions

A latest case of thyroid nodule intervention using Imbioray tiNK immune-trained NK cells intuitively demonstrates the actual effect of this technology, bringing new hope to more patients.

A 45-year-old male patient was found by thyroid ultrasound in a routine physical examination in August 2025: a nodule in the left thyroid lobe, about 3.5×2.6 mm, clear boundary, TI-RADS grade 3, classified as a benign nodule. Clinical advice was regular observation.

However, concerned about continuous nodule growth, the patient chose Imbioray tiNK immune-trained cell intervention after evaluating multiple options.

Starting from September 1, 2025, the patient received Imbioray tiNK immune-trained NK cell intervention at a dose of 5 billion units once a month.

In January 2026, follow-up thyroid ultrasound showed the nodule shrank to 2.3×1.9 mm, a reduction of 51.9%! After three interventions, the nodule shrank by more than half. Notably, the patient had no obvious discomfort during treatment, thyroid function remained normal, and quality of life was completely unaffected.

This case fully proves that for small benign thyroid nodules, NK cell intervention works quickly, gently reduces nodules, controls disease progression and avoids subsequent surgical risks. It is a safe, effective, controllable and accessible long-term management method for thyroid nodule patients.

Farewell to Nodule Anxiety:

NK Cell Intervention Opens a New Option

The high incidence of thyroid nodules has become a health issue that cannot be ignored. The traditional “wait-and-see” or “one-size-fits-all” treatment model is being replaced by more precise, safe and non-invasive disease management methods.

The innovative NK cell therapy is opening a new door for thyroid nodule patients. Relying on cutting-edge immune medical technology, with core advantages of non-invasiveness, safety and targeting, it provides a third solution for patients. Without surgery or lifelong medication, it gently regulates nodules, relieves anxiety and protects thyroid health.
